Guys I need some help like you would not believe,This thing is driving me nuts. I have a 89 stang with a B-cam,Pro-M 75mm mass air,65mm TB,AOD with 2800 stall. I have tried every way I know of to get this thing to idle right with out that damn surge. I have used a feeler guage set at .002 to set the idle screw and put the TPS at .95-.99,runs fine for a few seconds then she will start surging in gear out of gear then stall. I have tried using one of Fords bypass plates,it will idle decent then but has a small surge when I put it in gear and idles about 1,000 rpms. HELP...... Should I just take this B-cam out and put a different cam in?if so what?E-cam?Isky? Help!!!!!!!!!!!!!!!!!!!!!!!!!

Sorry, I meant in park or in drive,when you put your car in gear does it surge up some against the brake? Does your idle hang for a sec. when you rev. it up?

Thanks

I would suggest moving the throttle screw until you idle at about 900rpm. Mine is a T5, but I had this problem and that's what fixed it, mostly.
